CSA Global: Concept pit shell
7
Preliminary pit shell 4.2km x 1.2 km with a low strip ratio of 0.4 has been modelled
In June 2018, CSA Global completed an initial conceptual mining study using open cut optimisation techniques on the Central
vanadium deposit only (KRC ASX 20 June 2018).
This pit study enabled KRC to upscale our scoping work to almost twice the size of the operation modelled in a 2012 scoping
study.
----------------------
TSW Analytical has been working on two different HCl leach-chemical precipitation process routes to achieve high purity
vanadium pentoxide:
❖ A direct hydrous vanadium oxide route produced a high grade vanadium pentoxide (99.48% V2O5) (KRC ASX 24
February 2018)
❖ An ammonium metavanadate (AMV) process route is the current focus of our testwork and has produced a high purity
vanadium pentoxide (99.51% V2O5) product (KRC ASX 24 July 2018)
The production of high purity vanadium pentoxide has been the focus as it should be more readily converted into vanadium
electrolytes.
TSW Analytical is now focusing on producing steel grade vanadium pentoxide (+98% V2O5).
----------------------
Primero Group has delivered initial detailed process flow sheets for each stage of the beneficiation plant at Speewah. The
beneficiation circuit has been designed to maximise V and Ti recovery into the magnetite-ilmenite concentrate and reject a
high proportion of the ROM feed at 0.5mm by two stage grinding and magnetic separation methods (KRC ASX 20 June
2018).

Acid leaching of concentrates

KRC’s Vanadium testwork has examined a process flow sheet that processes high grade vanadium
samples from the Central Vanadium deposit (0.37-0.39% V2O5).
Initially a magnetite concentrate grading >2% vanadium pentoxide (V2O5) is produced by crushing,
grinding and magnetic separation methods.
The vanadium and titanium enriched concentrate is then leached in hydrochloric acid (at temperatures
between 70 and 90 degrees) to release the V, Ti and Fe metals into solution for separation by
hydrothermal and chemical precipitation methods.
This process is then followed by purification steps to produce high purity vanadium pentoxide (V2O5),
titanium dioxide (TiO2) and iron oxide (Fe2O3) products.
High Purity Titanium Dioxide
99.5% TiO2
High Purity Vanadium Pentoxide
99.51% V2O5
Our main objective is to outline a project that clearly differentiates ours from others around the globe.
The flat lying nature of the Speewah mineralisation gives King River Copper the opportunity to mine very large volumes of material
with minimum waste (0.4 tonne waste to 1.0 tonne mineralised material).
Metallurgical testwork and research has been ongoing on a number of fronts into the production of high purity Vanadium Pentoxide
powder (>99.5 V2O5) and standard grade Vanadium Pentoxide flake (>98% V2O5), as well as Titanium Dioxide products (pigment
grade and high purity >99% TiO2), iron oxide hematite and Vanadium Electrolyte (used in vanadium flow batteries)
An improved beneficiation flowsheet on high grade core has now produced a 2.11% V2O5 magnetite-ilmenite concentrate, at
higher mass yield of 16.5% at a coarser grain size (120 micron), and with more waste rejection (refer KRC ASX announcement 21
March 2018), compared with concentrates used in 2012. studies.
Direct hydrochloric acid leaching of concentrate has demonstrated V, Ti and Fe recoveries >96% at 9M acid strength, 90°C leach
temperature, 10% pulp densities under atmospheric conditions (refer KRC ASX announcements 21 August 2017, 9 October 2017,
4 December 2017, 30 January 2018, and 27 February 2018).
Hydrothermal precipitation testwork has produced a high purity titanium dioxide (99.5% TiO2) product (refer KRC ASX
announcement 30 January 2018) and further testwork is ongoing to improve recoveries and increase the grade. Research is also
underway to produce titanium metal sponge.
Chemical precipitation testwork has produced a high purity vanadium pentoxide (99.51% V2O5) by the Ammonium Metavanadate
(AMV) process route (KRC ASX 24 July 2018).
Test work and study progress

Nagrom have recently completed a baseline bottle roll sulphuric acid (H2SO4) leach test on a concentrate sample that assayed 1.7%
V2O5, 15.37% TiO2 and 60.04% Fe2O3, with 14.49% SiO2, 4.02% Al2O3, 3.77% CaO and 2.35% MgO.
After 58 days, leach efficiencies were 92% V, 76% Fe, 19% Ti, 49% Al, 44% Mg, 14% Ca and <1% Si.
-----------------
Bottle roll tests are currently underway on three much larger lump sizes of magnetite gabbro (P100 10mm, 5.6mm and 3.35mm)
assaying 0.36% V2O5, 3.65% TiO2, 21.37% Fe2O3, and 44.75% SiO2, 12.74% Al2O3, 8.36% CaO, 4.33% MgO, 2.32% Na2O and
1.12% K2O.
After 12 days the V and Ti are leaching slowly (as would be expected), with high leach rates for Fe, Al and Mg (KRC ASX 15 October
2018).
-------------------
These bottle roll tests are the first stage of testing into whether Speewah magnetite gabbro or a coarse concentrate are suitable for
heap or vat leaching.
Heap or vat leach operations have the potential to significantly lower capital and operating costs. KRC studies will examine this
process route into the production of vanadium pentoxide, titanium dioxide, iron oxide and possibly high purity alumina (HPA) products
using sulphuric acid leaching and solvent extraction methods.
Potential for heap or vat leaching

A very recent Scoping Study has outlined a path forward for the development of a Fluorite Project,
and the positive business case supports progression of that study towards a prefeasibility.
Indicated Mineral Resources represent 100% of planned mining scenario on existing mining
leases.
FLUORITE PROJECT
KRC owns 100% of the Windsor fluorite deposit at Speewah with a combined Indicated and
Inferred Mineral Resource of 6.7 million tonnes at 24.6% CaF2 (at 10% CaF2 cut-off grade),
comprising Indicated Resource of 4.1 million tonnes at 25.3% CaF2 and Inferred Resource of 2.6
million tonnes at 23.6% CaF2 (refer KRC ASX release 23 February 2018).
The deposit is located on existing King River Copper mining leases.

❖ RC drilling on the Trudi Vein has identified other high grade shoots and potential eastern
extensions (KRC ASX 12 October 2018):
• a new high grade zone at depth immediately east of the upper level high grade zone,
including 9m @ 2.78g/t Au including 1m @ 12.45g/t Au in KMRC182.
• deeper intersections below the Trudi Main Grid including 2m @ 5.64g/t Au with 1m @

• step out exploration 50m east of the main Trudi Grid returned 5m @ 1.78g/t Au including
1m @ 5.76g/t Au opening up new high-grade shoot exploration opportunities to the east.
❖ Follow up drilling of soil and rock sampling surveys which discovered the Jeniffer Vein has
returned gold mineralisation with grades up to 3.16g/t Au (KRC ASX 12 October 2018).
